WHEEL PLOW.

Application filed February 1, 1918. Serial No. 214,926.

T all whom it may concern Be it known that I, WALTER H. SILVER, acitizen of the United States, residing at Moline, in the county of RockIsland and State of Illinois, have invented certain new and usefulImprovements in Wheel Plows, of which the following is a specification,reference being had therein to the accompanyin drawing.

ly invention relates to wheeled plows, and more particularly to plows inwhich thepower of the draft is employed to raise the plow from theground, and the object of my invention is to provide a simple andeffective means by which the rear of the plow is raised practicallysimultaneously with the forward part thereof, and to a greater heightthan is ordinarily the case with the mechanism commonly employed.Referring to the drawings in which similar numerals indicate indenticalparts Figure 1 is a side elevation of a gang plow, with the land wheelremoved, embodylng my invention and illustrating the position of theparts when the plow is at work.

Figure 2 is a similar view showing the position of the parts when theplow is raised. Figure 3 is an enlarged detail plan of the rear wheel snport, and Figure 4 is a rear elevation of igure 3. I

To illustrate the application of my invention I have shown it as part ofa gang plow embodying, at the forward end thereof, a mechanism by whichthe front end of the plow is raised from the ground at will, which isthe subject of an application of Carl G. Strandlund, filed January 15,1915,

Serial No. 2343, patented -May 3, 1921, No.

1,376,787. to which reference is made for a full detail descriptionthereof, "and l'have used the same numerals inmy drawings as are foundin, the drawings of said application, for purposes of better reference,omitting a detailed'description of the parts. The plow beams 1, 2, and 3are connected to a draft bar 13, and spaced apart by suitable braces notshown, and carry plows a, b, and c. The forward end of the plow issupported on an axle 15 having a furrow wheel 1 1' and a land wheelnotshown. The axle is flexibl connected with the gang of plows in the f0lowingmanner, bails 35 are pivotally connected to the'axle 15 and to thebeams 1,2, and 3. Pivotally mounted forwardly on the beams 1 and '3respectively are levers 41 having a portion of their length, below theirpivots, bent at a rearward angle and pivotally attached to rearwardlyextending bars 42; the forward ends of the bars 42 extend beyond theaxle 15 and are in contact with the axle 15 except when the gang of lowsis out of the ground and their rear en 5 are movably secured to thebeams 1 and 3 respectively. Mounted on the beams 1 and 3, adjacent thelevers thereon are segmental racks 45 with the teeth of which dogs ofusual'type on the levers 41 are adapted to engage to hold the levers 41in any desired position of adjustment. Arms 48 and 52 are secured on atubular member through which the axle 15 passes, and have their freeends connected by a rod on which are rollers 50 and 51 normally incontact with the bars 42. A clutch mechanism is interposed between thelandward end of the tubular member and the hub of the land wheel and isadapted to be thrown in operation by actuation of a lever 59, resultingin the arms 48 and 52 rotating upward and forward and consequentlyraising the front end of the plow, the rear end being raised byindependent manually operated mechanism.

In my invention the rear end of the plow is raised racticallysimultaneously with the front end and by the same power, and to that endI mount rigidly, on the rear part of the landward bail 35, an uprightarm or standard 6 which is rockable forward or back by the movement ofthe bail 35 to which it is secured.

Rigidly mounted on the rear of the low, preferably on the plow beam 3,is a rame support composed of members 7 spaced apart rearwardly by atubular member 8 through which, and through the members 7, a bolt 9passes and is secured by a nut 10. A rocking lever 11 is pivotallymounted, intermediate its length, between the members 7 andis providedwith an eye at its upper end to receive a hook 12, the latter beingpreferably integral with a sleeve 13 mounted on a rod'16 the forward endof which is connected tothe arm 6. The sleeve 13 is loose upon the rod16 and has an adjustable and limited amount of lay thereon betweenadjustable stops 17 on t e'rod 16.

A rear furrow wheel 18 is mounted on a laterally extending ortion of acrank axle 19 which is substantially horizontal for a portion of itslength and is then bent upward at an an le to f g rm a spindle y hiph isjoyrnaled'gn feve20I The hpper eiid of the slee'vQO is" bifurcated toreceive the lower end of the rocking lever 11 to which it is"'liivofii-liy sec'illetlf 'Tlie loiver '13oi t'ion of the rocking lever11 eiitendingat a forward angle from the pivot of the lever to itspivotal connection with the sleeve 20.
